The weather agency is calling for 30 to 45 centimetres along Highway 3 between Paulson Summit to the Kootenay Pass.

Meanwhile, Allison Pass along the highway will be hit with freezing rain.

The Coquihalla is anticipated to be struck with below-zero temperatures following more than a day of snowfall, making for slushy and slippery conditions. A warm front should make its way through the region by the afternoon.

Parts of Highway 1 will be hit the hardest, with as much as 50 centimetres blanketing Rogers Pass. The highway between Revelstoke and Golden will be closed until 8 p.m., with no detour, as crews continue avalanche control.
